Improvement in metallic roofings



PATENT QEEICE.

HARRY D. COOK, OF NORMAL, ILLINOIS.

IMPROVEMENT IN METALLIC ROOFINGS.

Specification forming part of Letters Patent N o. 117,605, dated August1, 1871.

To all uhom it may concern:

Be it known that I, HARRY D. GooK, of Nor- Inal, of the county of McLeanand State of Illinois, have made certain Improvements in MetallicRoofing, of which the following is a specification:

My invention relates to the mode of fastening east-iron or othermetallic shingles upon the roof; and consists chieiiy ofthe use of twolugs upon the under side of the .shin gle, in combination with the nailfor fastening the 4shingle in place. The metallic shingles heretoforeused required to be fastened by driving the nail on the under side oftheshingle after it was laid in place upon the roof. This operation wasvery inconvenient, and it was also difficult to remove shingles thusfastened whenever it became necessary in repairing or raising the roof.This difficulty arose from the fact that each shingle had but one lug,and that was on the under side and near the lower end of the shingle,and was intended to fasten two shingles by laying one upon the other andthen secure both by a single nail or fastening' put into the lug of theupper shingle.

In the accompanying drawing, Figure l is a longitudinal section, whichshows the mode of fastening my shingles. Fig. 2 is a bottom view of myimproved shingle, and Fig. 3 is an end View of my shingle.

I propose to make my improved roofing of castironor other suitablemetal.

The main body A of the shingle may be one foot long and six inches wide,or of any other suitable dimensions, and of proper thickness. Along oneside of the shingle is a liange, B, and upon the other side a curvedlip, C, intended to fit over the iiange and thus make a water-tightjoint, 'which will not leak either from the accu- 1 innlation of meltingsnow upon the roof or during astrongwind with driving rain. On the underside of my shingle are two (or more) lugs, I) and E, one being near eachend ofthe shingle. These lugs have holes for the nail or fastening.

My shingles are laid as follows: In place of the ordinary closesheathing I use a series of ribs or strips, F, say about four or sixinches wide. These are laid at regular distances apart, inst the lengthof the shingles. The upper end of a shingle is seen at G, with its lug Dresting against the upper side ofthe rib F, and the nail or mfastening Kdriven in place. This nail is left projecting. say half an inch, inorder to receive the lug E of the next shingle L, and thus one nail orfastening holds two shingles. The shingle L is slipped into place afterthe nail is driven, and this prevents the necessity of driving the nailfrom the under side of the roof, and the shingle can be easily removed.After the shingle L is put in place the nail M is driven; then the neXtshingle N is put in pla-ce by slipping its lug E upon the nail M, whichthus holds two shingles. If it is desired to remove the shingles theymay all be easily taken off by beginning at the upper course andslipping each shingle in succession from the headless nails, without theuse of a hammer or any other tool. The nails or fastenings should bemade of suitable size and length, say about two inches long, and withouta head, so that the lug of the upper shingle may be slipped upon thenail after it is driven, and also to allow the removal of both shingleswithout drawing the nail. f

I do not limit my invention to the precise arrangement above described.I do not claim the overlapping of the top or upper end of each shingleby the base or lower end of the next above, nor do I claim the rib orilange B on the one edge and the covering-channel on the opposite edgethereof.

What I claim as my invention, and desire to secure by Letters Patent, is

l. The shingle L provided with its overlapping flange and lugs,constructed and applied to the roof in the manner described.

2. The series of shingles provided with lugs forth.
